Application June 30, 1948, Serial No. 36,139 claims. (ci. 229-16) This invention relates to containers composed of foldable material, such as paperboard, and particularly to containers suitable for such uses as for the packaging and sale of fruits and other foods, or for the packaging and deep-freezing of such articles.

It is a particular object of the present invention to provide a container of the class described composed of a minimum of parts which can be transported in a knocked down condition and thereafter can be quickly and conveniently erected and assembled for use with a minimum of skill, and which yet withal forms a rigid and rugged construction suitable for the use intended.

In general, my invention comprises a body com posed of a unitary blank cut and scored to deine a bottom and integral side walls, and a separate endless band adapted to embrace the side walls adjacent their upper edge portion to form a reinforcement, the side walls and the band being formed with complementary engagement means whereby the two components may be held 'lrmly interlocked.

A further object relates to the construction of the container in a manner whereby the side edges are retained in upwardly and outwardly in= clined position so that they may be internested after assembly and prior to iilling.

A further object relates to the construction oi the container whereby Ventilating openings are maintained between the adjacent side edges of the containers sidewalls.

Further objects relate to details of construction and arrangement of parts, the economies of construction and facility of assembly, as will be more apparent from the following specication and drawings, wherein:

Fig. 1 is a plan view of a blank employed in one form of my container.

Fig. 2 is a perspective View of an endless interlocking band employed in combination with the blank of Fig. 1 for erection thereof. Fig. 3 is a side elevational view of the erected container employing the components of Figs. 1 and 2, and Fig. 4 is an end elevational view thereof.

Fig. 5 is a section on the line 5-5 of Fig. 4 and Fig. 6 is a section on the line 6-5 of Fig. 3.

Fig. 'I is a plan view of a blank employed in a modified form of my container.

Fig. 8 is a perspective view of an endless inter-` locking band employed in combination with the blank of Fig. 7 for erection thereof.

Fig. 9 is a side elevational View of the erected container employing the components of Figs. 'I

and 8, and Fig. 10 is an end elevational view thereof.

Fig. 11 is a section on the line ii--H of Fig. 10

Fig. 12 .is a section on the line IZ-IZ of Fig. 9.

Referring to Figs. 1 to 6 of the drawings, the reference numeral I@ generally designates a blank cut and scored to define a base Ii having one opposed pair of side walls i`2|2 and another pair of opposed side walls iS-I3, all separated from each other at their side edges and integral with the vbase ii and defined therefrom and fold= able upwardly from the plane thereof on their respective score lines i-ii and |5-i5.

The blank i@ may be composed of such material as cardboard, and it may be provided with a moisture-proofing coating or impregnant such as a wax or a synthetic plastic. For the purpose of moisture resistance, the blank may be composed of laminated construction, including, for example, an intermediate ply of asphaltic material or the like well known moisture-resistant composite or laminated foldable material construction. The side Walls I2-i2 are further provided with slots i--lt medially of and par= allel to their outermost edges. Similarly, the side walls i--i are provided with slcts to deline the upwardly projecting tongues Il-Il inwardly of and adjacent and parallel to the outermost edges.

For the purpose of erecting the blank Iii into container form and for maintaining it in such position, I provide an elongated strip joined adhesively or by other means, as at i8, to form an endless band generally designated as i9 andsuitably scored as at 2i! to define four sections generally complementary tothe wall-formingv portions of the blank i9, that is, side wall portions 2i-2i and side wall portions 22-22. The sections of the band i8 are, however, each of slightly greater length than the width of the respective panels they are adapted to overlie so that when the side walls of the blank i0 are elevated and surrounded by the band I9 and engaged in operative position, the side walls of the container will extend in an upwardly and outwardly inclined position with their adjacent side edges in spaced relationship to provide ventilated openings as Aillustrated in Figs. 3 to 6.

The side walls 22-22 of the band L9 are formed with upwardly extending tongues 23-23 and are adopted to be inserted within the slots iS-M. Preferably, the length of the slots IG--IS are substantially equal to the widths of the tongues ll--ZI so that when they are inter-engaged lateral movement oi the band sections 22-22 will Thus, when the side walls oi' the blank Il are,I elevated and the endless band I8 engaged theref over and interlocked therewith by means or the 1;

aforesaid complementary tongues and slots, the

band I 9 will be held in restricted position up-"f'ffflllin wardly or downwardly with respect .to the side,

walls of the container and also against lateral movement thereon to provide a f'lrm and com!" pact construction composed of a minimum of parts and without bulk or exterior projections forming a simple nestable construction after assembly and immediately prior to filling.

If desired, as is well known, a transparent cover of suitable flexible material may be provided to retain the contents in the .container by adhering same to the bena ls after assembly, such es by heat-sealing or otherwise. Also, for the purpose of packaging food products for the purpose of deep-freezing, my container with its contents may be positioned within suitable closure envelopes or bags, while forming therein suitably rigid holding, positioning vor packaging means. Further, if desired, I may coat all or a portion of my container, after assembly, with suitable materia] to render vit moisture-resistant or waterproof, as by coating or dipping it in wax or plastic coatings or impregnants.

` Referring to the modified form of my invention shown by Figs. 7 to 12 of E,the drawings, the ref- `erence numeral 30 generally designates a blank cut and scored to define a base 3| having side walls 32--32 and 33-33. separated from each yother at their side edges and integral with the base 3| and defined therefrom and foldable upwardly from the plane thereof on their respective scored lines 34--34 and :i5-35. A

, .The side walls 32-32 are further provided with slots 36-36 medially of and parallel to their outermost edges. Similarly, the walls 33-33 are provided with slots to define the upwardly projecting tongues 31-31 inwardly of and adjacent nd parallel to the outermost edges.

For the purpose of erecting the blank 30 into container form and for maintaining it in such position, l'. likewise provide an elongated strip joined adhesively or by other means, as at 38,y

to form an endless band generally designated as 39 and suitably scored as at 40 to dene four sections generally complementary to the walli'orming portions of the blank 30, that is, portions 4I-4I and portions 42-42. The sections of the band 39 are, however, each of slightly greater length than the general width of the respective panels they are adapted to overlie but substantially equal to their Width at the end portions provided with the side edge tabs 44, so that when the side walls of the blank 30 are elevated nd surrounded by the band 39 and engaged in operative position, the side walls of the container will extend in an upwardly and outwardly inclined osition with their adjacent side edges in spaced relationship 5 to provide ventilated openings as illustrated in Figs. 9 to 12 but with the tabs of 'adjacent walls in abutment.

ananas The side walls 52-42 of the band 39 are formed with upwardly extending tongues 43--43 and are adapted to be inserted within the slots 36-36.

Thus, when the side walls of the blank 30 are elevated and the endless band 39 engaged thereover and interlocked therewith by means of the aforesaid complementary tongues and slots, the band I9 will be held in restricted position upwardly or downwardly with respect to the side lwalls of the container and also by reason of vclose 'nt against lateral movement thereon to provide Va firm and compact construction composed of a 'minimum of parts and without bulk or exterior projections forming a simple nestable construction after assembly and immediately prior to Although I have shown and described several.

. to those skilled in the art that other changes or modifications may be made in the details thereof without departing from the spirit of my invention.
